<p>
This screen allows you to configure the <a href="../../../start/concepts/pscan.html">passive scan</a> rules.<br>
</p>
<H3>Threshold</H3>
This controls how likely ZAP is to report potential vulnerabilities.<br>
<ul>
	<li>If you select Off then the scanner won't run.</li>
	<li>If you select Low then more potential issues will be raised which may increase the number of false positives.</li>
	<li>If you select High then fewer potential issues will be raised which may mean that some real issues are missed (false negatives).</li>
</ul>
